PTC Thermistors For Degaussing, Dual, Mono And Double Mono Cased
FEATURES
a. Dual or double mono PTC degaussing.
* Residual currents as low as 2 mA (p-p), ideal for high-resolution displays * Long decay time * Stable performance over a long time (>20000 operations) * Self-extinguishing white plastic case ("UL 94.V.0" )
MBB633
* Design-in support available.
APPLICATIONS
* Colour televisions
b. Mono PTC degaussing.
* Colour monitors.
DESCRIPTION
For good picture definition, colour televisions and monitors must be degaussed by a strong alternating magnetic field which gradually and symmetrically decays to a small value of residual current. This can be achieved by connecting a PTC thermistor in the degaussing circuit. The new generation of flat-screen, high-definition colour televisions and monitors require an excellent picture quality with high colour purity. This can only be achieved by a dual PTC device housing two PTC thermistors in intimate thermal contact, one being used to heat the other and so further reduce the residual current.
